TDK Corporation announces an extension to the PH-A280 series of high voltage input DC-DC converters. Capable of operating from 200 to 425Vdc, the new 3.3V, 15V and 28V output power modules are suitable for use in data centres, tele-communications and renewable energy applications utilising a 380V nominal high voltage DC bus.
The six new models are rated at 3.3V 15A or 20A, 15V 5A or 10A and 28V 2.7A or 5.4A. This extends the existing 50 to 150W PH-A280 product range of 5V, 12V, 24V and 48V outputs. The outputs of the new models can be adjusted by -20% to +10% (-10% to +20% for the 3.3V output) to accommodate non-standard voltages.
Following the industry standard quarter-brick package (37.2 x 12.7 x 58.3mm), the high efficiency units, up to 90%, can provide full load with -40°C to +100°C baseplate temperatures. The converters can also be conduction cooled making it suitable for use in sealed outdoor enclosures or liquid cooled applications.
Standard features include remote on-off, over-current, and over-voltage protection. All PH-A280 models carry a five-year warranty. The series is fully isolated with an input to output isolation of 3,000Vac and are safety certified to IEC/EN 60950-1, UL/CSA 60950-1 with CE marking for the Low Voltage and RoHS2 Directives.
